Thank you for your question!
Unfortunately, I'm not sure if a book like what you're seeking exists. As I understand, you're looking for something to get the basic concepts of various topics. Dummies books are geared, generally, towards 1 very specific topic.
If you're wanting to dive into the subject-matter, a bit, your best bet would probably be with one of our www.sybex.com or www.wrox.com titles. Wrox is more for programmers, and Sybex is geared towards IT Administration.
I hope this helps! Please let me know if you have any further questions. Have a great weekend!
Thank you for your time and help! Have a wonderful week.
